BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Chrysanthemum plant,botanically known as Chrysanthemum X morifolium, commercially grown as adisbudded potted Chrysanthemum plant and hereinafter referred to by thename ‘Fichrycosyel’.

The new Chrysanthemum plant is a product of a planned breeding programconducted by the Inventor in Fareham, Hampshire, United Kingdom and DeLier, The Netherlands. The objective of the breeding program is tocreate new potted Chrysanthemum plants with large incurveddecorative-type inflorescences.

The new Chrysanthemum plant is a naturally-occurring whole plantmutation of Chrysanthemum X morifolium ‘Fichrycospur’, disclosed in U.S.Plant patent application Ser. No. 15/732,509. The new Chrysanthemumplant was discovered and selected by the Inventor as a single floweringplant from within a population of plants of ‘Fichrycospur’ in acontrolled greenhouse environment in De Lier, The Netherlands during thespring of 2014.

Asexual reproduction of the new Chrysanthemum plant by terminalvegetative cuttings was first conducted in De Lier, The Netherlandsduring the spring of 2014. Asexual reproduction by terminal vegetativecuttings has shown that the unique features of this new Chrysanthemumplant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under allpossible combinations of environmental conditions and culturalpractices. The phenotype may vary somewhat with variations inenvironmental conditions such as temperature, daylength and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Fichrycosyel’. These characteristicsin combination distinguish ‘Fichrycosyel’ as a new and distinctChrysanthemum plant:

-   -   1. Relatively compact, upright and uniformly mounded plant        habit.    -   2. Moderately vigorous growth habit.    -   3. Uniform flowering habit.    -   4. Large incurved decorative-type inflorescences with        yellow-colored ray florets.    -   5. Response time about 56 days under controlled photoperiodic        treatments.    -   6. Good postproduction longevity.

Plants of the new Chrysanthemum can be compared to plants of themutation parent, ‘Fichrycospur’. Plants of the new Chrysanthemum differprimarily from plants of ‘Fichrycospur’ in ray floret color as plants of‘Fichrycospur’ have inflorescences with red purple-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants ofChrysanthemum x morifolium ‘Fichrycoswhi’, disclosed in U.S. Plantpatent application Ser. No. 15/732,509 with this application. Plants ofthe new Chrysanthemum differ primarily from plants of ‘Fichrycoswhi’ inray floret color as plants of the ‘Fichrycoswhi’ have inflorescenceswith white-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants ofChrysanthemum X morifolium ‘Zembla Yellow’, disclosed in U.S. Plant Pat.No. 14,733. In side-by-side comparisons, plants of the new Chrysanthemumdiffer primarily from plants of ‘Zembla Yellow’ in time to flower asplants of the new Chrysanthemum flower about four days later than plantsof ‘Zembla Yellow’. In addition, plants of the new Chrysanthemum aremore compact than plants of ‘Zembla Yellow’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of thenew Chrysanthemum plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Chrysanthemum plant. The photograph is a top perspective view ofa typical flowering plant of ‘Fichrycosyel’ grown in a 14-cm container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations andmeasurements describe plants grown during the summer in 14-cm containersin a glass-covered greenhouse in Fareham, Hampshire, United Kingdom andunder cultural practices typical of commercial potted Chrysanthemumproduction. During the production of the plants, day and nighttemperatures ranged from 17° C. to 21° C. and light levels averaged6,000 lux. Plants were grown under long day/short night conditions forabout two weeks and then grown under short day/long night conditions toinduce inflorescence initiation and development. Plants were not pinchedand were ten weeks old when the photograph and detailed description weretaken. In the following description, color references are made to TheRoyal Horticultural Society Colour Chart, Fifth Edition, except wheregeneral terms of ordinary dictionary significance are used.
